The judge handed down the 8-year term last month for Koch, who had pleaded guilty this summer to aggravated domestic battery and other charges stemming from the beating her 23-month-old child received in October 2010 at the St. Charles motel where Koch and the boyfriend were living.

Koch’s boyfriend, James Cooper, an admitted heroin abuser, confessed to punching the child numerous times in the head, causing permanent brain damage.

He is serving a 15-year prison term.

Although Koch, 30, did not participate in the beating, authorities said she lied to police about Cooper’s whereabouts and failed to protect her daughter.

The 8-year sentence Koch received represented an extended term, beyond the usual 3- to 7-year sentence on her charges.

But the judge said that, upon reconsideration, Koch did not deserve that long of a sentence because she had no prior criminal record and she had completed some counseling, according to Lovig.

Prosecutors confirmed that the sentence had been reduced, but declined further comment. By law, Koch must serve 85 percent of her sentence, about 3 years and 3 months.

In a speech that stirred political controversy in two countries, Israeli Prime Minister Benjamin Netanyahu told Congress on Tuesday that negotiations underway between Iran and the United States would "all but guarantee" that Tehran gets nuclear weapons to the detriment of the entire world.
